Article Of Footwear With Cleat Arrangement Including Angled Cleats

ABSTRACT

An article of footwear with an arrangement of cleats is disclosed. The arrangement of cleats may enhance traction during the first step of sprinting, quick directional changes, and backward movement. The arrangement of cleats may be disposed on a base plate and may include a first angled cleat aligned with the hallux of a user and a second angled cleat disposed proximate a rearward edge of the base plate. The first angled cleat and two flat cleats may be aligned with the perimeter of a circle on the forefoot region of the base plate.

BACKGROUND

The present invention relates generally to an article of footwear and, more particularly, to a sports shoe with cleats.

Articles of footwear having cleats have previously been proposed. While conventional cleats generally help give sports shoes more grip, the cleats do not necessarily optimize traction during the first step of sprinting or when a wearer is moving backward. Moreover, the cleats doe not necessarily provide traction in an optimal way during quick directional changes. It would be advantageous for a sports shoe to have cleats that optimize traction during the first step of sprinting, backward movement, and quick directional changes.
